Insure a decat

[RetroPug]

Me personally not worried about insurance cover. But my point is we don't need dpf's like we don't need Egr's they just something else to go wrong so if you making engine as efficient as it can be why should that be classed as a mod

Classing something as a modification has nothing to do with how sensible or not it is, it is simply as the name suggests, a change made to the car that makes it different o original factory spec.

The thing is if that's the case changing tyre brands is a mod to.

What I'm saying is the dpf is a non item on ours as it doesn't regenerate it just clogs up. A new one costs 145 or a de cat pipe costs 50. The benefits of doing a de cat is a more efficient engine and one less thing to go wrong.

I wouldn't class it as serious mod I would class it like the example I used of changing tyre brand. No where near the same as say suspension, bigger alloys or remap....

Some insurers try to argue that changing tyre brands or sizes is a modification.
It could be argued that tyres are consumables though.

At the end of the day, what constitutes a modification and what is replacing wear items is not always clear cut, but deliberately altering the exhaust system would be viewed as a modification by insurers and the authorities I think, regardless of whether the intent is boy racer noise or efficiency.
